Counterbalance shaft bearings breakdown in Nov 2009 and had repairs done at independent repair shop; August 2010 cylinder head leak/crack which brings oil to water coolant. Repair shop advised to get rid of car 2005 xc 90 v8 Volvo. I am fearful of driving this car. To repair and replace engine and new transmission too much $$$ for this Volvo. With no guarantee. Volvo needs to own up to the bad quality of this particular model. I feel it is dangerous to drive with so many cars on the road. It's an accident waiting to happen.
